SDR10EZPJ4R3 Equivalent & Substitute Parts Reference

Part Overview

The SDR10EZPJ4R3 from Rohm Semiconductor is an active automotive AEC-Q200, pulse withstanding thick film chip resistor. It features a resistance of 4.3 Ohms ±5%, rated for 0.5W power in an 0805 (2012 Metric) package. Due to fluctuating inventory, supply chain constraints, or design redundancy requirements, sourcing parametric equivalent or substitute parts is essential to maintain assembly continuity and compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for chip resistors in the 0805 (2012 Metric) package is strictly determined by matching core electrical, mechanical, and compliance parameters. The parameters used to group substitutes include manufacturer, resistance value, tolerance, power rating, film composition, automotive certification, package size, temperature coefficient, operating temperature range, and moisture sensitivity. Only parts with explicit matches on these criteria are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both SDR10EZPJ4R3 and ESR10EZPJ4R3 are active products from Rohm Semiconductor, offering 4.3 Ohms ±5% resistance and automotive AEC-Q200 qualification. The main difference is the power rating: SDR10EZPJ4R3 is rated at 0.5W, while ESR10EZPJ4R3 is rated at 0.4W. Both parts meet the specified requirements for automotive pulse withstanding resistors in the 0805 (2012 Metric) package and are compliant with MSL 1 and ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: What are the key parameters required for substituting SDR10EZPJ4R3 in an automotive application?
A: The substitute must match resistance (4.3 Ohms), tolerance (±5%), composition (Thick Film), automotive certification (AEC-Q200), package size (0805), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity (MSL 1).
